Question — Decretum of Gratian
Question III
GRATIAN. But as to the question whether after the handing over it is lawful for him, with the abbot’s permission, to return to his own property, it is easily shown that this cannot be done. For returning itself is criminal. But one who ceases to oppose a manifest crime when he can do so consents to it. Yet this abbot not only does not oppose it, but even by permitting it becomes an abettor. Therefore the abbot is not permitted to give anyone permission to go back, and thus that person is not permitted to go backward, because from the time he once subjected himself to the abbot, he can do nothing without the abbot’s permission.
GRATIANUS. Quod autem queritur, an post traditionem sit ei fas cum licentia abbatis ad propria redire? facile monstratur fieri non posse. Ipsum enim redire criminosum est. Qui autem manifesto facinori desinit obuiare, cum potest, consentit. Hic autem non solum non obuiat, sed etiam permittendo fautor existit. Non ergo licet abbati dare licentiam alicui retro abeundi, nec itaque illi licet retrorsum abire, quia ex quo semel se abbati subiecit, absque eius permissione nichil agere potest.
